Chanta
Last updated: 2026-08-18Chanta requires every meld and the pair to contain a 1, 9, or honor, with at least one honor in the hand. 2 han closed; 1 han open. Opposes Tanyao. See Riichi Mahjong Yaku Guide.
Requirements
- Four melds + pair; each group contains a terminal (1, 9) or honor
- Hand must include at least one honor (all terminals, no honors → junchan, higher han — not in this batch)
- 2 han closed; 1 han open
Valid example
Each sequence contains 1 or 9; south pair (z2) adds an honor — chanta (2 han closed).
Invalid or confusing
No honors; every group has 1/9 — junchan (3 han) + pinfu, not chanta (chanta requires an honor).
Stacking and open hands
Open play loses 1 han. Can stack with pinfu, yakuhai, etc. Opposite route from tanyao — terminal-heavy play.
Scoring
Fu follows normal rules; with pinfu, watch the wait. See Fu Calculation Basics.
